Brief Summary
The mechanism involved in the development of tardive dyskinesia (TD) is complicated. It now seems that several neurotransmitter systems may be affected, including dopaminergic, noradrenergic, gamma-amino-butyric acid (GABA) ergic, cholinergic and peptidergic pathways. Piracetam (2-oxo-pyrrolidone) is a nootropic drug structurally related to GABA. It has been used clinically to treat a wide range of diseases and conditions, mainly in treatment of organic brain syndrome, myoclonus, memory impairment, post-concussional syndrome, vertigo, alcohol withdrawal, cerebrovascular insufficiency, hypoxia, intoxications of different origins or mechanic brain injures. Piracetam is cerebral homeostatic normalizer, neuroprotectant, cerebral metabolic enhancer and brain integrative agent. It enhances brain energy, especially under deficit condition: hypoxia, chemical toxicity or impaired cerebral microcirculation; preserve, protect and enhance synaptic membrane and receptor structure and plasticity. It has various effects on glutamate neurotransmission on micromolar levels piracetam potentiates potassium-induced release of glutamate from hippocampal nerves. It is an oxidant agent and may be useful for treatment TD. Piracetam is among the toxicologically safest drugs ever developed even in mega doses. Data derived from some clinical reports have suggested that piracetam can improve symptoms and is effective agent for treatment of different movement disorders including acute neuroleptic induced extrapyramidal symptoms and TD. The doses that used for TD treatment varied from 800 mg/day to 24000 mg/day. According to these findings the symptoms of TD disappeared in the period of 3-7 days. To date there was only one double-blind crossover study regarding use of piracetam for treatment TD that was conducted almost 20 years ago. The findings of this study were impressive, but to our knowledge nobody reproduced these results.
Detailed Description
We intend to examine 40 inpatients, aged 18-75 years old, suffering from TD and its variants. Criteria for inclusion into the study will be: a) DSM-IV diagnosis of tardive dyskinesia; b) stable psychotropic regimen of a month prior to entry into the study; c) duration of TD of at least 1 year; d) all patients had to be hospitalized. Exclusion criteria will be: a) evidence of family history of Huntington's disease; b) evidence of substance or alcohol abuse; c) patients who received any form of vitamin medication; d) patients with concurrent medical illness or neurological disorders that may have influenced up the diagnosis of tardive dyskinesia. The study design will be a double blind, randomized crossover group study and will be last for 8 weeks. This period provided an opportunity to exclude the influence of spontaneous fluctuations in the severity of TD. Full physical and laboratory examinations were performed on all inpatients in the beginning and at the end of the trial. Psychotropic medication will be maintained at fixed doses throughout the duration of study. The capsules preparations will be made by a professional pharmacist in the same size and color capsules in individual number-coded packages. The capsules will be added to the patients' usual medications and will be given by nurses. Assessments for tardive dyskinesia and its variants will be done using Extrapyramidal Symptom Rating Scale (ESRS) at baseline and repeated every week, prior crossover, and then every week. This scale was developed by G. Chouinard and A. Ross-Chouinard (15) and was designed to rate three types of extrapyramidal symptoms: parkinsonian, dystonic and dyskinetic. Although the scale may be applied to non-drug-induced extrapyramidal symptoms, its sensitivity has been most often assessed in the evaluation of drug-induced extrapyramidal symptoms. The dose of piracetam or placebo will be increased every week on 2000 mg up to 8000 mg/day in dependence on the changes of movement disorders. The doses of their neuroleptic medications not will be change a month before and during the research. The patients will take piracetam or placebo as addition to their constant medication. It should be emphasized again that improvement of TD symptoms after piracetam addition was appeared through very short period (3-7 days) in comparison to other medications used for treatment of TD. Moreover, if efficacy of piracetam will be proved in our study, clinicians obtain a new, effective, safe drug for TD treatment with rapid onset of the action. References Lohr JB.
